摘　　要：脉冲Nd∶YAG四倍频激光(266nm)泵浦D2的受激拉曼散射第二级斯托克斯光(316.39nm)用作O3差分吸收激光雷达的λoff。为研究D2的受激拉曼散射效应和定量解释其物理机制作了一系列的实验。通过调节泵浦能量和气体压强,得到了各级散射光的能量转换效率,找到了第二级斯托克斯光的优化条件。The second Stokes radiation （ S2,316. 39 nm） of SRS of D2, pumped by a pulsed Nd： YAG laser at 266 nm,is used λoff as of O3 - DIAL. A series of experiments are reported here on the generation of Stokes orders generated in D2 , aiming to explain qualitatively the practically important physical behavior of the configuration. By adjusting pumping laser energy and the pressure of gas, the energy conversion efficiency of scattering radiation is obtained. Finally, the appropriate condition to optimize S2 is found.
